WAGON-WHEEL.

SPECIFICATION forming part of Letters Patent No. 353,744, dated December 7, 1886.

Application ined August 21, isst.

To all whom t may concern:

Be it known that I, ALBERT Coon HALL, of Denver, in the county of Arapahoe and State of Colorado, have invented a new and Imn proved Wagon-Vheel, of which the following is a full, clear, and exact description.

Reference is had to the accompanying drawA ings, forming a part of this specication, in which similar letters of reference indicate corresponding parts in all the gures.

Figure lis a partial side elevation of my im- Fig. 2 is adiametrical section. Fig. 3 is a partial plan view. Fig. 4 is a longitudinal section of one of the spokes. Fig. 5 shows three views of the felly F. E3 is a section of the form it is rolled. F is a section of the form it is made to assume and the form used on the wheel. E isa plan of felly, and shows the lugs E*,which occur on the felly only where the spokes join it.

The objects of my invention are, rst, to provide a light, durable, and strong wagonwheel entirely of metal 5 second, to provide a wheel in which the tendency to crystallize is reduced to a minimum; third, to provide a wheel on which the tire is independent of the mechanismof the felly and spokes, and on which new tires can be placed at any time.

My invention consists in the combination, with a metallic hub and spokes clamped to.- gether, of a metallic felly formed in thedshape of the letter U, secured by rivets around the outer ends of spokes, all as hereinafter fully described. Said hub consists of the box H,having a shoulder formed on theinner end and a thread and nut on the outer end. Surrounding this box arethree collars, D, C, and B. D bears against the shoulder of the box H. A nut, I, on the outer end of the box bears against the collar B. They are thereby clamped. together. These collars being clamped tightly together, holes are drilled through at a slight angle, said holes being a trie smaller than the tenons A of the metallic spokes A, of which Fig. 4 is a section. Vhen the spokes are put in place, the collars are separated, the spokes placed between them. The holes in the collars then clasp the tenons of the spokes very tightly before the collars come together.

The metallic spokes A are made of metallic Serial No. 211,47. (No model.)

tubing. They are contracted near their ends, forming tenons A and A, Fig. 4. Thesetenons may be rolled or stamped in the hot metal.

The` metallic felly F is U-shaped in form, and is made as illustrated in Fig. 5. The lugs E* are placed exactly opposite each other, but do not meet. A hole is drilled through them at a slight angle, the size of the tenons on the spokes. A hole is also drilled through the bottom of the felly the size of the spoke. When the spokes are to be putin place, the felly is sprung apart enough to allow the large end of the spoke to pass through the small hole in the lugs. The felly is then broughtback to its correct form, and two rivets, G, (shown in the' elevation, Fig. 1, and partial plan, Fig. 3,) are placed one on each side of the lugs and riveted while hot. This forces the lugs of the felly tightly around the tenons of the spokes. The wheel is then placed in a lathechuCk, and the ends of the spokes passing through the collars are turned to t tightly on the box H. The periphery ofthe felly and the extremities of the spokes are also turned round and even. A tire can then be placed on the Wheel in the usual manner.

The hub ends of the spokes are arranged in alternation near the inner and outer ends of the hub to brace the wheel laterally and increase its strength.

The hub I-I and collars have been patented, and I am at present an owner in the patent. During extensive experiments made by myselfwith metallic wheels this hub was used and gave perfect satisfaction. The spokes experimented with were solid and of different crosssection, and were connected to the tire by be ing screwed into it after passing through a wooden felly. The end of the spoke passing through the collars hada head formed on it. This head was made to bear against the under side ot' the collars by being screwed into the tire. These wheels would rattle very badly,

and the spokes would crystallize in a few days. It is believed that the metallic tube and felly in combination with this hub, all arranged as shown and described in this specitlcatiomwill obviate these difficulties.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- IOC) l. The metallic tubular spokes A, having contracted circular tenons A near each end, substantially as herein set forth and described.

2. The metallic felly F, U-shaped in crosssection, having inwardly-projecting lugs, as E4, rplaced at equal distances apartupon its circumference, said lugs having grooves tting the tenons of the spokes and made to securely clamp these tenons by means of rivets passing through the sides of the felly upon each side of the spokes. 3. The combination of the metallic tubular spokes A, having tenons formed near each end, with the metallic Ifelly F, having inwardlyprojecting lugs with holes passing through them, and having rivets, one on each side, substantially as herein set forth.

Vlugs arranged to secure the outer ends'of the spokes.
